I just updated from 2.6.8-gentoo-r10 to 2.6.9-gentoo and noticed that the kernel hangs for about 30 seconds during ide device discovery. I attached my .config and dmesg output (in which I marked the position where it hangs) Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: Kernel hangs for 30 seconds. Expected Results: Kernel did not do that before.

Could you please see if this issue exists in development-sources-2.6.9?
Yes, the vanilla 2.6.9 kernel has the same problem.
Then it appears to be an upstream issue, as opposed to something wrong with our patchset. Could you please open a bug for this at http://bugzilla.kernel.org ? Thanks. If you get a solution, let me know, and I'll consider patching gentoo-dev-sources
